never heard of a bodybuilder who takes a lot of soy protein powder.
There are vegatarian bodybuilders... Not saying they look that great. I think most of them are natties too.
Personally, i throw in some soy now and then for some variety. Wouldn't use it as a staple protein source though.
Read that it has similar qualities as casein.
supposedly the soy also makes kids look younger than they are, as evidenced by 1988+ or so when they started adding soy to all the milk thats given to young babies. Like if you look at 18 year old kids today, they look like they are 14 or so for the most part
I've had this thought as well, but i don't know if this is really true. Probably just in my mind.
You also have to consider that a lot of kids nowadays survive on simple carbs and unhealthy fats.
What IS true definately is that the puberty age of girls keeps going down. Don't know if this correlates to soy. There are a lot of other chemicals (in plastics, beauty products, shampoos, cleaning products, ...) around us that have estrogen-like activities.
